Decode Base64 back to text
Base64 is everywhere — JWTs, Basic Auth headers, CSRF nonces, signed URLs, cookies, OAuth state, opaque tokens of every shape. When you need to peek inside one to debug an issue, this decoder is the fastest path. Paste the string in, get the original UTF-8 back, copy or download the result.
The reverse tool is Text to Base64 — encode any UTF-8 string into the standard or URL-safe alphabet.
